Nemesia plant named ‘Easter Bonnet’

ABSTRACT

A new  Nemesia  plant particularly distinguished by a prolific display of bi-colored flowers whose upper petal is soft lavender pink and lower petal is a contrasting cream white with a prominent orange-yellow eye, and strongly fragrant flowers, is disclosed.

Genus and species: Nemesia foetens.

Variety denomination: ‘Easter Bonnet’.

BACKGROUND

The present invention relates to a new and distinct cultivar of Nemesia plant grown as an ornamental for use in garden and landscape borders, or in containers. The new variety is known botanically as Nemesia foetens and will be referred to hereinafter by the variety name ‘Easter Bonnet’.

‘Easter Bonnet’ resulted from a formal breeding program begun by the inventor in 1998 at her nursery in West Sussex, United Kingdom. The purpose of the breeding program is to produce new varieties of Nemesia that exhibit compact habit and new flower colors and color combinations.

In 2011, the inventor conducted a controlled cross-pollination between two unreleased and unpatented selections of Nemesia from the inventor's breeding program, namely Nemesia code number ‘1100’ (unpatented) as the male parent and Nemesia code number ‘1156’ (unpatented) as the female parent. ‘Easter Bonnet’ was selected by the inventor in 2012 for its attractive bi-colored flowers and prominent orange-yellow eye. In addition, ‘Easter Bonnet’ exhibits an upright compact rounded habit, medium-green leaves, and strongly fragrant flowers.

‘Easter Bonnet’ was first asexually propagated by the inventor in 2012 in an unheated greenhouse at the inventor's nursery in West Sussex, United Kingdom using softwood cuttings. The inventor has determined that ‘Easter Bonnet’ is stable and uniform, and reproduces true to type in successive generations of asexual reproduction via softwood cuttings.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Easter Bonnet’. ‘Easter Bonnet’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.

-   -   1. ‘Easter Bonnet’ exhibits a compact upright habit.     -   2. A 6 months old plant of ‘Easter Bonnet’ grown in a 9 cm         container is 15 cm in height and 10-12 cm in width.     -   3. A 9 months old plant of ‘Easter Bonnet’ grown in a 13 cm         container is 25-30 cm in height and 18-20 cm in width.     -   4. ‘Easter Bonnet’ exhibits bicolor flowers which have a soft         lavender pink upper petal and a creamy white lower petal.     -   5. The flowers of ‘Easter Bonnet’ exhibit a prominent         orange-yellow-colored palate or “eye”.     -   6. ‘Easter Bonnet’ is floriferous.     -   7. ‘Easter Bonnet’ flowers are pleasantly fragrant with a         vanilla scent.     -   8. ‘Easter Bonnet’ has a long blooming period, from early spring         until fall.     -   9. ‘Easter Bonnet’ is hardy to −6° Celsius and survives in USDA         Zone 9.

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

‘Easter Bonnet’ is distinguishable from the male parent, ‘1100’ (unpatented) as follows: whereas the flowers of ‘Easter Bonnet’ are bi-colored exhibiting a soft lavender pink upper petal and a cream white colored lower petal, with an orange-yellow eye, the flowers of the male parent exhibit a pink upper petal and pale yellow lower petal. Additionally ‘Easter Bonnet’ exhibits an upright compact habit with strongly fragrant flowers, whereas ‘1100’ has a more open, less compact habit and significantly less scented flowers.

‘Easter Bonnet’ is distinguishable from the female parent, ‘1156’ (unpatented) as follows: whereas the flowers of ‘Easter Bonnet’ are bi-colored with a soft lavender pink upper petal and a cream white colored lower petal, with an orange-yellow eye, the flowers of the female parent are entirely mauve in color. Additionally, ‘1156’ exhibits a dwarf habit, growing to an average of 15 cm at maturity while ‘Easter Bonnet’ averages 25 to 30 cm at maturity.

The closest comparison plant known to the inventor is the inventor's variety, ‘FLEURIPI’ (U.S. Plant Pat. No. 16,851). ‘FLEURIPI’ is distinguishable from ‘Easter Bonnet’ as follows: Mature plants of ‘FLEURIPI’ are shorter in height than plants of ‘Easter Bonnet’. ‘FLEURIPI’ has strong pink colored flowers compared to ‘Easter Bonnet’ which has bi-colored flowers with a soft lavender pink upper petal and a cream white colored lower petal, with a prominent orange-yellow eye. 

I claim:
 1. A new and distinct cultivar of Nemesia plant named ‘Easter Bonnet’ as described and illustrated herein.
